[0001] The utility model relates to the technical field of prefabricated beam end mold construction, in particular to a chamfering construction device suitable for a box beam end mold. Background Art

[0002] With the continuous improvement and reform of infrastructure, some technical defects are inevitable in the construction process; in the process of prefabrication of box girders, it is easy for the finished beam concrete to frequently fall off corners and pieces, which affects the overall appearance and reduces the quality of the prefabricated box girders.

[0003] In order to further improve and optimize the box girder end formwork and avoid the vibration of mechanical equipment caused by the improvement of the box girder, which may cause the box girder end formwork to shift, thereby affecting the improvement effect of the box girder end formwork, multiple processing is required, which increases unnecessary consumables and reduces the optimization efficiency. Utility Model Content

[0004] In order to solve the technical problem that when the existing equipment is performing box girder end mold optimization, the box girder end mold is offset due to vibration during the optimization operation, thereby reducing the optimization efficiency and increasing consumables, the utility model provides a chamfering construction device suitable for the box girder end mold.

[0005] The utility model adopts the following technical scheme to achieve: a device suitable for chamfering the end mold of a box beam, comprising:

[0010] Through the above technical solution, the equipment can quickly fix the box beam end mold with the cooperation of its own positioning mechanism, so as to facilitate the subsequent improvement operation; and the cleaning mechanism can be used to quickly clean the surface of the box beam end mold to reduce the adverse effects on the box beam end mold during the improvement; refer to Figure 6-Figure 8Based on the existing technology, the arc area of ​​the end mold of the end box beam is chamfered 45° to match the straight chamfer, and a small triangle (3cm*2cm*2cm) is welded to extend the chamfer at the intersection of the bottom web chamfer; this solves the problem of corner and piece falling off that is easy to occur in the demoulding process of the finished beam, while reducing labor costs and repair costs. On the other hand, the overall appearance of the end mold is improved, which greatly improves the appearance of the finished beam. Before installation, first place the end mold on a flat operating table, use the cleaning mechanism to clean the debris on the end mold surface of the end box beam to ensure the level, cooperate with the positioning mechanism to achieve adaptive positioning and fixation, and use a steel stylus to draw the reference lines on the box beam end mold in sequence, draw lines around the end mold to make grooves, the groove depth is 2mm, and then weld the chamfers. The welding process is divided into two layers. The first layer is uninterrupted welding, and the second layer needs to be overlapped in sections with a lap length of 3cm. After welding is completed, use a grinder to grind and polish all around. In order to reuse the end mold for a long time in the future, it is necessary to apply engine oil in time to prevent the chamfers from decaying.

[0014] As a further improvement of the above solution, the output end of the driving motor is connected to a belt pulley and a gear in sequence, the gear is meshed with a rack plate, and the rack plate is installed on the top of the clamping arm.

[0015] Through the above technical solution, the sliding of the connecting slide rod and the connecting slide groove is utilized to ensure the meshing connection between the gear and the rack plate to drive the entire cleaning assembly to move and clean.

[0016] As a further improvement of the above scheme, a belt is sleeved on the outer side of the first belt pulley, and a second belt pulley is sleeved on the other side of the belt. A connecting rod is fixedly connected to the outer side of the second belt pulley, and the connecting rod is rotatably connected to the inner side of the mounting frame.

[0017] As a further improvement of the above scheme, the cleaning assembly includes connecting slots, which are opened on both sides of the clamping arm, and the two groups of connecting slots are respectively slidably connected with a cleaning roller 1 and a staggered groove. One side of the cleaning roller 1 is fixedly connected to the second belt pulley, the inner side of the cleaning roller 1 is hollow, and a connecting protrusion is arranged inside the cleaning roller 1.

[0018] Through the above technical solution, it is ensured that the driving force for rotation is provided for the cleaning roller one and the cleaning roller two by the transmission of the belt pulley one, the belt and the belt pulley two.

[0019] As a further improvement of the above scheme, it is characterized in that the cleaning roller one is horizontally slidably connected to the cleaning roller two by means of a connecting protrusion, staggered grooves are evenly arranged on the outer side of the cleaning roller two, and rubber protrusions are staggered on the outer sides of the cleaning roller one and the cleaning roller two for cleaning the end mold of the box girder.
